Thanks for the nice comment. People don't realize that there are about 30 minutes of editing time for every minute of video posted. It's a lot of work. I've really enjoyed the Firefly. Concerning registration, the Firefly certainly can be built under Part 103, or so they say. But, you have to work really hard to keep the weight legal. Many people will get close, but go over, and just call it good enough. The proverbial "fat ultralight." But, I wanted electric start, full enclosure, brakes, oversized tires with metal rims, full castering tail wheel, 10 gallons of fuel, and a transponder (required in my area). That put me far enough outside the Part 103 weight limit that I registered it. Plus, ultralights still have a bad rap from the 80's. I find there's a stigma around the airport I fly at. Your experience may vary. So, by registering it, it says "I have a pilot's license... I've been trained... I know the rules, etc." I have a PPL, so it wasn't a big deal for me to do. It will probably hurt the resale value though. The Aerolite 103 would be a good choice these days. It's kind of the best "traditional" looking ultralight going these days. If you buy new it will build quickly. If you build a Firefly, you will be building for a while. The covering process takes a long time. Slip on sails are nice... Of course, you get a much more finished/refined look with traditional covering. Choices, choices, choices... In the end, whatever you end up with, you will probably enjoy it.

Dave Doyle Yes sir.
